The snow is falling, and if you have to clear it off your car for the first time ever tomorrow morning (and if not, you will have to soon) clear all the snow off the roof, windows, all the windows, and the hood. If you omit to remove snow from the hood and roof, it will blow on the windshield as you drive and fall over the windshield when you brake.
This might be the most crystal clear concept to you, the Minnesota native or alumni of previous winters. But it continues to escape the many new motorists peering through the little holes on their car that are driving around after every snowfall. Perhaps you can be excused the first time (as long as you don't cause an accident) but please be safe and get all that nasty cold white stuff off your car before you drive off this winter. Minnesota's other road users thank you.
